Experimental and Theoretical Research on Open Resonators

摘要

The scalar integral equations for open resonators are derived. The complex eigenvalue determines power loss and phase shift per transit. The eigenfunction represents the field distribution on a reflector. This distribution is used to calculate the field inside the resonant volume. An experimental setup to measure the resonant frequencies and the quality factors was designed. The field was scanned with small spheres. The quality, the resonant frequency and the amplitude of the signal were recorded simultaneously. Data agree with the theoretical ones.
